Quality Control

Our 1,8-Biphenylenediboronic Acid is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and ICP-MS for heavy metal screening, to ensure it meets the stringent requirements of research and production. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon or nitrogen) for long-term stability and to prevent degradation. Keep the container tightly sealed in a desiccator when not in use.
